This Privacy Policy describes how Slack collects, uses and discloses information, and what choices you have with respect to the information.

Updates in this version of the Privacy Policy reflect changes in data protection law. In addition, we have worked to make the Privacy Policy clearer and more understandable by:

organizing it into the sections listed in the Table of Contents below,

providing a series of examples that help illustrate how the policies may be implemented by Slack and

defining and capitalizing a few terms that are used more than once for simplicity and brevity.

When we refer to “Slack”, we mean the Slack entity that acts as the controller or processor of your information, as explained in more detail in the “Identifying the Data Controller and Processor” section below.

Applicability Of This Privacy Policy

This Privacy Policy applies to Slack’s online workplace productivity tools and platform, including the associated Slack mobile and desktop applications (collectively, the “Services”), Slack.com and other Slack websites (collectively, the “Websites”) and other interactions (e.g., customer service inquiries, user conferences, etc.) you may have with Slack. If you do not agree with the terms, do not access or use the Services, Websites or any other aspect of Slack’s business.

This Privacy Policy does not apply to any third party applications or software that integrate with the Services through the Slack platform (“Third Party Services”), or any other third party products, services or businesses. In addition, a separate agreement governs delivery, access and use of the Services (the “Customer Agreement”), including the processing of any messages, files or other content submitted through Services accounts (collectively, “Customer Data”). The organization (e.g., your employer or another entity or person) that entered into the Customer Agreement (“Customer”) controls their instance of the Services (their “Workspace”) and any associated Customer Data. If you have any questions about specific Workspace settings and privacy practices, please contact the Customer whose Workspace you use. If you have an account, you can check http://slack.com/account/team for contact information of your Workspace owner(s) and administrator(s). If you have received an invitation to join a Workspace but have not yet created an account, you should request assistance from the Customer that sent the invitation.

Information We Collect And Receive

Slack may collect and receive Customer Data and other information and data (“Other Information”) in a variety of ways:

Customer Data. Customers or individuals granted access to a Workspace by a Customer (“Authorized Users”) routinely submit Customer Data to Slack when using the Services.

Other Information. Slack also collects, generates and/or receives Other Information:

Workspace and Account Information. To create or update a Workspace account, you or your Customer (e.g., your employer) supply Slack with an email address, phone number, password, domain and/or similar account details. For details on Workspace creation, click here. In addition, Customers that purchase a paid version of the Services provide Slack (or its payment processors) with billing details such as credit card information, banking information and/or a billing address.

Usage Information.

Services Metadata. When an Authorized User interacts with the Services, metadata is generated that provides additional context about the way Authorized Users work. For example, Slack logs the Workspaces, channels, people, features, content and links you interact with, the types of files shared and what Third Party Services are used (if any).

Log data. As with most websites and technology services delivered over the Internet, our servers automatically collect information when you access or use our Websites or Services and record it in log files. This log data may include the Internet Protocol (IP) address, the address of the web page visited before using the Website or Services, browser type and settings, the date and time the Services were used, information about browser configuration and plugins, language preferences and cookie data.

Device information. Slack collects information about devices accessing the Services, including type of device, what operating system is used, device settings, application IDs, unique device identifiers and crash data. Whether we collect some or all of this Other Information often depends on the type of device used and its settings.

Location information. We receive information from you, your Customer and other third-parties that helps us approximate your location. We may, for example, use a business address submitted by your employer, or an IP address received from your browser or device to determine approximate location. Slack may also collect location information from devices in accordance with the consent process provided by your device.

Cookie Information. Slack uses cookies and similar technologies in our Websites and Services that help us collect Other Information. The Websites and Services may also include cookies and similar tracking technologies of third parties, which may collect Other Information about you via the Websites and Services and across other websites and online services. For more details about how we use these technologies, please see our Cookie Policy.

Third Party Services. Customer can choose to permit or restrict Third Party Services for their Workspace. Typically, Third Party Services are software that integrate with our Services, and Customer can permit its Authorized Users to enable and disable these integrations for their Workspace. Once enabled, the provider of a Third Party Service may share certain information with Slack. For example, if a cloud storage application is enabled to permit files to be imported to a Workspace, we may receive user name and email address of Authorized Users, along with additional information that the application has elected to make available to Slack to facilitate the integration. Authorized Users should check the privacy settings and notices in these Third Party Services to understand what data may be disclosed to Slack. When a Third Party Service is enabled, Slack is authorized to connect and access Other Information made available to Slack in accordance with our agreement with the Third Party Provider. We do not, however, receive or store passwords for any of these Third Party Services when connecting them to the Services. For more information on Third Party Services, click here.

Contact Information. In accordance with the consent process provided by your device, any contact information that an Authorized User chooses to import (such as an address book from a device) is collected when using the Services.

Third Party Data. Slack may receive data about organizations, industries, Website visitors, marketing campaigns and other matters related to our business from parent corporation(s), affiliates and subsidiaries, our partners or others that we use to make our own information better or more useful. This data may be combined with Other Information we collect and might include aggregate level data, such as which IP addresses correspond to zip codes or countries. Or it might be more specific: for example, how well an online marketing or email campaign performed.

Additional Information Provided to Slack. We receive Other Information when submitted to our Websites or if you participate in a focus group, contest, activity or event, apply for a job, request support, interact with our social media accounts or otherwise communicate with Slack.

Generally, no one is under a statutory or contractual obligation to provide any Customer Data or Other Information (collectively, “Information”). However, certain Information is collected automatically and, if some Information, such as Workspace setup details, is not provided, we may be unable to provide the Services.

How We Use Information

Customer Data will be used by Slack in accordance with Customer’s instructions, including any applicable terms in the Customer Agreement and Customer’s use of Services functionality, and as required by applicable law. Slack is a processor of Customer Data and Customer is the controller. Customer may, for example, use the Services to grant and remove access to a Workspace, assign roles and configure settings, access, modify, export, share and remove Customer Data and otherwise apply its policies to the Services.

Slack uses Other Information in furtherance of our legitimate interests in operating our Services, Websites and business. More specifically, Slack uses Other Information:

To provide, update, maintain and protect our Services, Websites and business. This includes use of Other Information to support delivery of the Services under a Customer Agreement, prevent or address service errors, security or technical issues, analyze and monitor usage, trends and other activities or at an Authorized User’s request.

As required by applicable law, legal process or regulation.

To communicate with you by responding to your requests, comments and questions. If you contact us, we may use your Other Information to respond.

To develop and provide search, learning and productivity tools and additional features. Slack tries to make the Services as useful as possible for specific Workspaces and Authorized Users. For example, we may improve search functionality by using Other Information to help determine and rank the relevance of content, channels or expertise to an Authorized User, make Services suggestions based on historical use and predictive models, identify organizational trends and insights, to customize a Services experience or create new productivity features and products.

To send emails and other communications. We may send you service, technical and other administrative emails, messages and other types of communications. We may also contact you to inform you about changes in our Services, our Services offerings, and important Services-related notices, such as security and fraud notices. These communications are considered part of the Services and you may not opt out of them. In addition, we sometimes send emails about new product features, promotional communications or other news about Slack. These are marketing messages so you can control whether you receive them.

For billing, account management and other administrative matters. Slack may need to contact you for invoicing, account management and similar reasons and we use account data to administer accounts and keep track of billing and payments.

To investigate and help prevent security issues and abuse.

If Information is aggregated or de-identified so it is no longer reasonably associated with an identified or identifiable natural person, Slack may use it for any business purpose. To the extent Information is associated with an identified or identifiable natural person and is protected as personal data under applicable data protection law, it is referred to in this Privacy Policy as “Personal Data.”

Data Retention

Slack will retain Customer Data in accordance with a Customer’s instructions, including any applicable terms in the Customer Agreement and Customer’s use of Services functionality, and as required by applicable law. Depending on the Services plan, Customer may be able to customize its retention settings and apply those customized settings at the Workspace level, channel level or other level. Customer may also apply different settings to messages, files or other types of Customer Data. The deletion of Customer Data and other use of the Services by Customer may result in the deletion and/or de-identification of certain associated Other Information. For more detail, please review the Help Center or contact Customer. Slack may retain Other Information pertaining to you for as long as necessary for the purposes described in this Privacy Policy. This may include keeping your Other Information after you have deactivated your account for the period of time needed for Slack to pursue legitimate business interests, conduct audits, comply with (and demonstrate compliance with) legal obligations, resolve disputes and enforce our agreements.

How We Share And Disclose Information

This section describes how Slack may share and disclose Information. Customers determine their own policies and practices for the sharing and disclosure of Information, and Slack does not control how they or any other third parties choose to share or disclose Information.

Customer’s Instructions. Slack will solely share and disclose Customer Data in accordance with a Customer’s instructions, including any applicable terms in the Customer Agreement and Customer’s use of Services functionality, and in compliance with applicable law and legal process.

Displaying the Services. When an Authorized User submits Other Information, it may be displayed to other Authorized Users in the same or connected Workspaces. For example, an Authorized User’s email address may be displayed with their Workspace profile. Please consult the Help Center for more information on Services functionality.

Collaborating with Others. The Services provide different ways for Authorized Users working in independent Workspaces to collaborate, such as shared channels. Other Information, such as an Authorized User’s profile Information, may be shared, subject to the policies and practices of the other Workspace(s).

Customer Access. Owners, administrators, Authorized Users and other Customer representatives and personnel may be able to access, modify or restrict access to Other Information. This may include, for example, your employer using Service features to export logs of Workspace activity, or accessing or modifying your profile details. For information about your Workspace settings, please see https://slack.com/account/settings.

Third Party Service Providers and Partners. We may engage third party companies or individuals as service providers or business partners to process Other Information and support our business. These third parties may, for example, provide virtual computing and storage services. Additional information about the subprocessors we use to support delivery of our Services is set forth at Slack Subprocessors.

Third Party Services. Customer may enable or permit Authorized Users to enable Third Party Services. When enabled, Slack may share Other Information with Third Party Services. Third Party Services are not owned or controlled by Slack and third parties that have been granted access to Other Information may have their own policies and practices for its collection and use. Please check the privacy settings and notices in these Third Party Services or contact the provider for any questions.

During a Change to Slack’s Business. If Slack engages in a merger, acquisition, bankruptcy, dissolution, reorganization, sale of some or all of Slack’s assets or stock, financing, public offering of securities, acquisition of all or a portion of our business, a similar transaction or proceeding, or steps in contemplation of such activities (e.g. due diligence), some or all Other Information may be shared or transferred, subject to standard confidentiality arrangements.

Aggregated or De-identified Data. We may disclose or use aggregated or de-identified Other Information for any purpose. For example, we may share aggregated or de-identified Other Information with prospects or partners for business or research purposes, such as telling a prospective Slack customer the average amount of time spent within a typical Workspace.

To Comply with Laws. If we receive a request for information, we may disclose Other Information if we reasonably believe disclosure is in accordance with or required by any applicable law, regulation or legal process. Please see the Data Request Policy to understand how Slack responds to requests to disclose data from government agencies and other sources.

To enforce our rights, prevent fraud, and for safety. To protect and defend the rights, property or safety of Slack or third parties, including enforcing contracts or policies, or in connection with investigating and preventing fraud or security issues.

With Consent. Slack may share Other Information with third parties when we have consent to do so.

Security

Slack takes security of data very seriously. Slack works hard to protect Other Information you provide from loss, misuse, and unauthorized access or disclosure. These steps take into account the sensitivity of the Other Information we collect, process and store, and the current state of technology. Slack has received internationally recognized security certifications for ISO 27001 (information security management system) and ISO 27018 (for protecting personal data in the cloud). To learn more about current practices and policies regarding security and confidentiality of the Services, please see our Security Practices. Given the nature of communications and information processing technology, Slack cannot guarantee that Information, during transmission through the Internet or while stored on our systems or otherwise in our care, will be absolutely safe from intrusion by others.

Age Limitations

Identifying The Data Controller And Processor

Data protection law in certain jurisdictions differentiates between the “controller” and “processor” of information. In general, Customer is the controller of Customer Data. In general, Slack is the processor of Customer Data and the controller of Other Information. Different Slack entities provide the Services in different parts of the world.
